In concentric contraction, muscle tension is sufficient to overcome the load, and the muscle shortens as it contracts. [8] This occurs when the force generated by the muscle exceeds the load opposing its contraction. During a concentric contraction, a muscle is stimulated to contract according to the sliding filament theory. This occurs ...
A study was performed to test how eccentric and concentric contractions affect cardiac autonomic modulation after exercise. Men (aged 18–30) were divided into four groups: concentric control, eccentric control, concentric training, and eccentric training. Results concluded that resistance training (eccentric contractions) promoted strength gain.
A near isotonic contraction is known as Auxotonic contraction. There are two types of isotonic contractions: (1) concentric and (2) eccentric. In a concentric contraction, the muscle tension rises to meet the resistance, then remains the same as the muscle shortens.
In an eccentric movement, the force of the contraction is less than the force giving upon it, so the muscle can lengthen at an appropriate time,” says Guillermo Escalante, DSc, C.S.C.S., a ...
The speed of the switching is extremely fast, 0.20 seconds or less. For example, high-level sprinters execute the switch from the eccentric contraction that occurs when the foot hits the ground to the concentric contraction when the foot breaks contact with the ground in less than 0.10 seconds.
This theory has been largely rejected, as concentric contractions which also produce lactic acid have been unable to cause DOMS. [5] Additionally, lactic acid is known from multiple studies to return to normal levels within one hour of exercise, and therefore cannot cause the pain that occurs much later.

A stretch-shortening cycle (SSC) is an active stretch (eccentric contraction) of a muscle followed by an immediate shortening (concentric contraction) of that same muscle. Research studies [ edit ]
